A theoretical model is presented for magnetoelectric (ME) effects in multi-push-pull mode magnetostrictive/piezo-fibre laminate composites. Analytical solutions for the ME coefficient (alpha(ME)) were derived. The effects of thickness ratio of the magnetostrictive phase, Kapton and multiple layers of epoxy on the value of aME were discussed. Experimental results agreed well with the theoretical analysis. When the thickness ratio of the magnetostrictive phase was v = 0.63, alpha(ME) was found to have a maximum value of 25.6Vcm(-1) Oe(-1). For thinner Kapton and epoxy layers, the values of alpha(ME) became higher. This model presents theoretical guidelines by which one can achieve higher values of aME.
